All Implemented Interfaces:

ConversionProcessor, Processor<ParsingContext>

public abstract class MasterDetailProcessor
extends AbstractMasterDetailProcessor<ParsingContext>

A RowProcessor implementation for associating rows extracted from any implementation of AbstractParser into MasterDetailRecord instances.

For each row processed, a call to AbstractMasterDetailProcessor.isMasterRecord(String[], Context) will be made to identify whether or not it is a master row.

The detail rows are automatically associated with the master record in an instance of MasterDetailRecord.

When the master record is fully processed (i.e. MasterDetailRecord contains a master row and all associated detail rows), it is sent to the user for processing in AbstractMasterDetailProcessor.masterDetailRecordProcessed(MasterDetailRecord, Context).

Note this class extends ObjectRowProcessor and value conversions provided by Conversion instances are fully supported.
